2 seconds

9.812 m/s²

9.7989 m/s²

Explanation:

L = Length of pendulum

g = Acceleration due to gravity

T = Time period would be 1+1 = 2 seconds

Time period is given by

$T=2\pi\sqrt{\dfrac{L}{g}}\\\Rightarrow g=4\pi^2\dfrac{L}{T^2}\\\Rightarrow g=4\pi^2\dfrac{0.9942}{(1+1)^2}\\\Rightarrow g=9.812\ m/s^2$

The free fall acceleration in Cambridge is 9.812 m/s²

$T=2\pi\sqrt{\dfrac{L}{g}}\\\Rightarrow g=4\pi^2\dfrac{L}{T^2}\\\Rightarrow g=4\pi^2\dfrac{0.99284}{(1+1)^2}\\\Rightarrow g=9.7989\ m/s^2$

The free fall acceleration in Virginia Beach is 9.7989 m/s²

The expression the courage to fail is very cheap is a sentence. If only the courage to fail is underlined, however, then it is a noun phrase, and functions as the subject of this sentence.
